详细
The method of synthesis of nanoscale titanium dioxide from organic precursor using supercritical fluid technology was suggested. It was demonstrated that the obtained product consists of amorphous particles with a narrow size distribution. It possesses a high porosity and a large value of specific surface area. The effect of temperature, pressure, and concentration of the titanium(IV) isopropoxide precursor on the average size of TiO2 nanoparticles has been studied. The method allows preparation of titanium dioxide free from precursor compounds. Complex physico-chemical study of the obtained product has been performed.
